Uniqueness for the spatially homogeneous Boltzmann equation in critical Sobolev spaces

Tianhao Dong, Shuchen Guo, Jie Ji

We study the spatially homogeneous Boltzmann equation without angular cutoff for very soft potentials satisfying the inverse power law relation $γ + 4 s = 1$ . Our main results establish…

Equilibria and linear stability for the Boltzmann equation with radial anharmonic confining potentials

Ling-bing He, Jie Ji, Wu-wei Li

We study the Boltzmann equation in the whole space under the radial anharmonic confining potentials $Φ (x) = ∣ x ∣^{p} / p$ for $p > 2$ and $Φ (x) = ⟨ x ⟩^{p} / p$ for $1 < p < 2$ . We first c…

Runaway avalanches in plasmas with external electric fields: spatially inhomogeneous case in a perturbation framework

Ling-Bing He, Richard M. Höfer, Jie Ji +1

We consider the Landau-Coulomb equation for a (hydrogen) plasma heated by an external electric field. In this setting, theoretical and experimental results in plasma physics show t…
